His work was used to increase potential energy of the weight, therefore you can calculate like W=mgh=281.5x9.81x0.171 J
I have heard that the work done later on by his dentist to fix his dentures was quite hard

a follow up question was
(b) What total force was exerted on arfeuille's teeth during the lift
what does that mean?

The forced exerted was exactly F=mg=281.5 x 9.81 Newtons

It means that a downward force equal to the weight he lifted will be exerted on his teeth (the contact point).

I have to see under which conditions was the test carried out. I am not too sure neck muscles can stand that force
